IMPROVEMENT IN DUMPING-CARS.

Specification forming part of Letters Patent No. 140,779, datedJuly 15,1873; application filed March 12, 1873.

' To all whom it may concern do hereby declare that the following is afull,

clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings making a part of thisspecification, and to theletters and figures of reference markedthereon.

Figure 1 of the drawings is a representation of a top view of my dumpingarrangement for cars. Fig. 2 is a sectional View of the same. Fig. 3 isan end view of the same.

My invention relates to certain improvements in dumping-cars, such asare used in the construction of embankments for railroad tracks 5 and itconsists in the arrangement of shields or coverings for the upper axlesalso, the construction and arrangement of the brakes for'engaging withthe upper wheels and holding the car in position.

In the drawing, A represents a dumpingcar, similar in generalconstruction to those in ordinary use, having two opposite sides, a a,hinged at top and provided with buttons at bottom, so that the load maybe dumped on either side. der side of the car project feet B, in thelower ends of which are journaled wheels I), which run on rails or sillscm the lower part of a frame-work, 0. Attached to the frame-work besidethe rails c and extending up above them are bars D, the upper'edges ofwhich are horizontal for about three-fifths of their length, incliningdownward at each end at an angle of about forty-five degrees. The upperedges of these bars D are toothed for engagement with toothed wheels Eattached to the endsof axles which extend entirely through the car fromend to end above the floor of the car, passing through the end pieces,so that the two Wheels E at each end are at a distance apartcorresponding with the length of each inclined portion of the toothedThe two axles to which the four wheels E are attached are located nearthe longitudinal center of the car, and are incased in shields orcoverings G to protect them from From the four corners of the un- ,endpieces of the car.

injury, which shields may be solid bars with their ends attached totheend pieces of the A car and the axles running through them, or they maybe hollow casings placed around said axles. These coverings are angularin shape, and the apex is directly above the longitudinal center of theaxle, thereby serving not only as an ordinary shield for the axle, butalso as slide-ways, aprons, or guides for the falling dirt.

When the car is in place upon the frame in a level position it issupported in the center by the wheels E and at the corners by the wheelsb. It is held in place by a brake at each end, consisting of a bar orplate, H, attached to the end piece by set-screws passing through slotsh, said bar or plate being adj ustable vertically by means of a lever,J, pivoted on the end piece or bar D, so that the plate H may be raiseduntil its upper end engages between the two wheels E E, and prevents.

their movement in either direction. A bar, L, has its ends fastened tothe ends of the bar D, and passes over the wheels E and prevents theirvertical displacement.

The teeth may be omitted from the edge of the barD, and the wheels maybe smooth pulleys, if desired.

In the bottom of the car is a sliding door, M, the ends of which run ingrooves in the This sliding bottom is provided with suitable devices bywhich it may be moved back and forth to drop the load from the center,when desired, and held in place when not in use.

This car is arranged to travel transversely across the track, so as todeposit the load on either side or between the rails, as desired.

The frame-work may be attached directly to the trucks, or it may beplaced upon an ordinary platform-car, so as to be removed at pleasure.

The operation of dumping the car is as follows: After the car is loadedand ready for operation the gear-wheels E E are operated by means ofcranks or any other suitable devices over the horizontal toothed portionof the bar D, the forward Wheel at each end of the car, then descendingthe incline at the end of the slot at an angle of about forty-five de.
